THE PROBLEM:Incomplete
combustion or poor draft due to inadequate combustion air in too-tightly
constructed buildings can result in carbon monoxide creation, poor
equipment efficiency, reduced equipment life and nuisance service calls.

THE SOLUTION:The IN-FORCER
mechanically draws outside air indoors on demand to provide fresh air
for safe and efficient operation of fuel burning equipment.

Pricing is based on fan sizing with basic controls needed for the
primary appliance and/or any additional appliance.
A single residential appliance needing a PAI-1O/2O or PAI-1G/2G with
controls ranges $350-$450.
Add $125-$200 in controls to add an additional appliance.
Provide BTU input for appliance(s) for a proper quote.
Usually ships UPS Ground.
No tax out of NY.

Step 3) Referencing Table C and your calculated
equivalent length, verify that the CFM performance listed in
Table C is equal to or greater than that
determined in Table A. Select Model PAI-1 or PAI-2 Series
based on CFM necessary and control circuit
voltage.

CALCULATING EQUIVALENT LENGTH (TABLE B)

The performance shown is based on
equivalent feet. To determinethe equivalent
feet of an installation add the length of the 3" PVC inlet pipe plus the
equivalent length of any elbows. Do not include the intake elbow or gooseneck
equivalent loss, they have already been factored into the performance data. Use
the same method to determine the equivalent feet if a 6" outlet duct is
installed.
